ROBERT RILEY, OF BURNLEY, ENGLAND.-

RING SPINNING, DOUBLING, AND TWISTING MACHINE.

To all whom it may concern:

Be it known that I, ROBERT RILEY, a subject of the King of Great Britain and Ireland, and a resident of Burnley, in the county of Lancaster, England, have in vented new and useful Improvements in Ring Spinning, Doubling, and Twisting Machines, of which the following is a specification.

This invention relates to improvements in that type of traveler for use in a ring spinning, twisting or doubling machine which consists of a member adapted to bridge over or to cross the ring and to have one end movable in the plane of the ring toward and away from the spindle.

It consists in forming such traveler with a movable joint or hinge in its length where it crosses the ring, of such a nature as to permit one end of the traveler to have angular movement relatively to the other end in the plane of the ring and thus give the greatest amount of freedom to the delivery end of the traveler and permit this end to easily and freely move in the plane of the ring toward or away from the cop or spindle, and close on to the nose of the cop.

My improved traveler is particularly adapted for use in the formation of weft and twist cops on a bare spindle.

The accompanying drawings illustrate a traveler of the hitherto known type but provided with a joint according to my invention.

Figure 1 shows one form of the improved traveler (without the ring) in position and winding a cop on a bare spindle. Fig. 2 shows in perspective the same traveler in position on its ring and winding on the bare spindle. Fig. 3 shows the traveler in its ring, and the latter in cross section. Fig. 4 is a view of the traveler by itself. Fig. 5 is a view to an enlarged scale of a modified form of improved traveler, but instead of being made out of wire as illustrated by the preceding drawings it is made out of sheet metal. Fig. 6 is a view of the end of such a traveler. Fig. 7 is a view from above.

A indicates the traveler, B the ring, C the cop and D the spindle. One end E, the delivery end, of the traveler is formed as an open fork which will permit this end to freely slide upon or about the ring B according to the varying diameters of the surface being wound upon and accordlngly as Specification of Letters Patent.

it is required to approach to or recede from the spindle. The other end, F, of the traveler is formed with an approximately C- shaped, or equivalent eye to fit over and engage with the ring as shown. At a point between the delivery end and fork of the traveler and its end F, a movable joint or hinge is formed in it as shown at G. This joint is of such a nature as to freely permit the independent movement of the de livery end of the traveler in a plane which is about the plane of or is about parallel to the plane of the ring or about perpendicular to the axis of the spindle. Such joint or hinge is preferably near the end F.

H indicates the yarn passing from its thread guide to the eye F, thence to the delivery end E, and from there to the cop or spindle but the yarn may otherwise be engaged by or with the traveler.

The traveler and its joint or hinge may be produced in many various and suitable ways. As is shown to an enlarged scale in Figs. 3 and 4 for ease of reference a wire traveler may have its eye end F produced by bending a single piece of wire as shown. The other part of the traveler may be of two pieces of wire twisted together to form the fork end E and to form small loops 6 e to loosely engage with the eye, one on each side of the bend f therein.

WVhen the traveler is of thin sheet metal as shown in Figs. 5, 6, and 7, the joint or hinge may be formed by hooking one part of the traveler into the other in such a manner as to permit the required movement of the delivery end. The limbs of the forked parts of this traveler may be separately twisted longitudinally through an angle of 90 and rounded on their inner surfaces, as shown in Fig. 6 which is one end view of E, and also in Fig. 7 so as to reduce friction on the ring.

Any suitable type of ring may be employed with the new traveler but I prefer a ring which will be tightly gripped in the split spring plate P and will rest by a shoulder thereon and which is internally grooved as at J. This groove may, at certain stages of the winding, permit the central portion of the traveler to enter it, thus enabling a small ring to be used or a cop to beproduced which is larger than could otherwise be bound in a ring of like flange diameter.

Although the improved traveler is only described and illustrated as for the spinning and winding of a cop on a bare spindle, its uses for spinning and winding yarn into other forms and under other conditions will be understood.

lVhat I claim is 1. In a ring spinning, doubling and twisting device, a ring in combination with a jointed traveler 'adapted to bridge across said ring, the ends of said traveler being engageable with said ring and with the yarn and the joint thereof being disposed between said ends, whereby to permit angular movement of one end of the traveler relative to the other end, in the plane of the ring, substantially as described.

2. In a ring spinning, doubling and twisting device, a ring in combination with a jointed traveler adapted to bridge across said ring, one end of said traveler having an eye to engage such ring, and the other end having a fork adapted to embrace said ring and to permit of lateral movement of this end of said traveler across said ring, said traveler being jointed between its ends, whereby to permit of angular movement of the forked end relative to the eye,.in the plane of the ring, substantially as described. In witness whereof I have hereunto set my hand in the presence of two witnesses.
